Lycopodiella inundata expands its areal on the European North-East of Russia. In the subzone of the middle taiga of the Komi Republic in 2017-2018, four local populations of this species were found, associated with anthropogenic ecotopes, poor and acidic sands, or peat, varying in moisture regime. Obligatory satellites of L. inundata in plant communities are Drosera rotundifolia L. and Juncus filiformis L., mosses of the genera Sphagnum L. and Polytrichum Hedw. Its local populations are small, beyond protection areas of the Komi Republic and so are endangered. The life-form of the Lycopodiella inundata sporophyte is a spore variance of perennial plant with annual shoot system. This species prefers vegetative multiplication through natural winter morphological disintegration. For determine the population in the beginning of shoots growth, ramets are recommended to be counted. The paleo-geographic analysis makes it possible to exclude the relic nature of the present locations of L. inundata in the European North and allows one to classify the species as an allochthonous element of the flora. In view of the fact that the species is rare and tends to decrease its habitats worldwide, we included L. inundata into new edition of the Red Data Book of the Komi Republic with protection status category 3 (Rare). All habitation places of the species are out of specially protected areas of the republic and so are threatened. Limiting factors for this stenotopic species in the Komi Republic are its narrow ecological amplitude, low competitiveness, instability to violations of the hydrological regime (bogging or draining) and overgrowth of biotopes due to natural succession processes.
